Leuconostoc mesenteroides

 

Leuconostoc mesenteroides is a species of lactic acid bacteria associated with fermentation, under conditions of salinity and low temperatures (such as lactic acid production in fermented sausages). In some cases of vegetable and food storage, it was associated with pathogenicity (soft rot, slime and unpleasant odor). L. mesenteroides is approximately 0.5-0.7 µm in diameter and has a length of 0.7-1.2 µm, producing small grayish colonies that are typically less than 1.0 mm in diameter. It is facultatively anaerobic, Gram-positive, non-motile, non-sporogenous, and spherical. It often forms lenticular coccoid cells in pairs and chains, however, it can occasionally forms short rods with rounded ends in long chains, as its shape can differ depending on what media the species is grown on. L. mesenteroides grows best at 30°C, but can survive in temperatures ranging from 10°C to 30°C. Its optimum pH is 5.5, but can still show growth in pH of 4.5-7.0.

Cancer Risk: Acrylamide AGEs

Minimizing Cancer Risk: Understanding the Relationship Between Acrylamide, Advanced Glycation End Products, and Cooking Tips Tweet Follow @AZSPerformance In recent years, concerns about cancer risk associated with dietary choices have gained significant attention. Researchers have identified two substances, acrylamide and advanced glycation end products (AGEs), that are formed during certain cooking processes and have been linked to an increased risk of cancer. In this article, we will explore the connection between acrylamide, AGEs, and cancer, as well as provide practical tips to help you reduce your exposure to these potentially harmful compounds. Acrylamide and Cancer Risk: Acrylamide is a chemical compound that forms naturally during high-temperature cooking methods, such as frying, baking, and roasting. It is commonly found in foods like potato ...

Occipital lymph nodes

The occipital lymph nodes are located on the back of the head close to the margin of the trapezius and resting on the insertion of the semispinalis capitis. Their afferent vessels drain the occipital region of the scalp, while their efferents pass to the superior deep cervical glands.

Lactococcus lactis

  Lactococcus lactis is a Gram-positive bacterium used extensively in the production of buttermilk and cheese, but has also become famous as the first genetically modified organism to be used alive for the treatment of human disease. L. lactis cells are cocci that group in pairs and short chains, and, depending on growth conditions, appear ovoid with a typical length of 0.5 - 1.5 µm. L. lactis does not produce spores (nonsporulating) and are not motile (nonmotile). They have a homofermentative metabolism, meaning they produce lactic acid from sugars. They've also been reported to produce exclusive L-(+)-lactic acid. However, reported D-(−)-lactic acid can be produced when cultured at low pH. The capability to produce lactic acid is one of the reasons why L. lactis is one of the most important microorganisms in the dairy industry. Based on its history in food fermentation, L. lactis has generally recognized as safe (GRAS) status, with few case reports of it being an opportuni...
